ADOLPH Z. GERMAINS, OF LONDON, ENGLAND.

SMOKE-'CONSUMING AND FUEL-SAVING DEVICE.

SPECIFICATION forming part of Letters Patent No. 689,299, d t d D b 17, 1901.

Application filed September 15, 1900. I Serial No. 30,191. (No'modeld To all whom it may concern: I

Be it known that I, ADOLPH ZALKIN GER- MAINS, a subject of the Queen of Great Britain, residing at London, in the county of Middlesex, England, have invented certain new and useful Improvements in Smoke-Consuming and Fuel-Saving Devices, of which the Fig. 3 is a similar view with still other parts removed. Figs. 4. to 13 are views of the various parts detached, Fig. 12 being a top plan view with the upper part of the device removed. Fig. 14. is a full-length vertical section showing all of the parts in place.

The upper part of the apparatus is formed of the parts a and d, each of which is approximately hemispherical in shape, with their edges facing each other, but separated by bars 0. leaving an open space between the This open circular space is covered by a perforated damper e,'connected by pins e to the forked ends of the lever e, arranged to be operated by a chain c by an attendant below. The lever e is pivotally attached to a curved bracket 0 In actual use a hood or shield c is placed over the upper part of the device, being attached to the part a. by slotted lips c and buttons a. In this hood there is of course a vertical slot in which the lever e may play. On the hood 0 are hooks c, to which stay-ropes may be fastened.

Below the part dis a perforated damper 61 which may be arranged to slide around the stem of the device, if desired, for the purpose of varying the draft. Below the damper d is a pipe d, which expands downwardly, as shown at f, forming a bell-shaped chamber open at its lower end. Into this chamber projects the socket-tube it, slightly cutaway at the top, as shown at W, and secured to the tube or pipe d by means of bolts and staypieces f Around the socket-tube h is the sliding tube g, arranged to slide up around the tube and to entirely close the openings between the tubes h and 01 if desired. This tube g is carried on the ends of a forked lever g, adapted to be operated by the chain "9 from below. The lever g is pivoted in a curved bracket f, fastened to the part f. The tube g is prevented from moving down too far by the pins t" in the tube 2', which is adapted to fit into or over the upper end of the chimney. The tube It is slightly coned, the larger part being uppermost, so that it will fit into the tube 2'. 0

Within the part (Z are arranged a series of fans, preferably five in number, as shown in Fig. 12. The largest fan 12 is located in the center, and the other fans 19 and b are arranged in pairs, which, however, alternate with each other. On these fans are cupshaped blades. By means of the fans and the adjustable dampers 6, 61 and g, together with the opening in the bottom of the pipef, Iam enabled to exactly regulate the draft, save fuel, and to a large extent prevent smoke. I am unable to give the exact scientific reasons; but I have found by experiment that these parts must be differently adjusted under varying conditions, such as the speed of movement of the boat, (provided this apparatus has been used on the smoke-stack ofa boat,) the direction and intensity of the wind, the dampness of the atmosphere, &c. After an intelligent attendant, however, has received a little instruction he finds no difliculty whatever in regulating the apparatus.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a smoke-preventing and fuel-saving device, the combination of bell-shaped parts oppositely disposed and leaving an opening between them, of a perforated damper arranged over this opening, means for moving said damper, and a shield covering said damper but at a distance therefrom.

2. In a smoke-consuming and fuel-saving device, the combination of a tube adapted to fit into or over a chimney or smoke-stack, said tube being closed at the top but provided with a series of side openings, dampers for fit into or over a chimney or smoke-stack, said tube being provided with two side openings, an adjustable damper for each of said openings, means for movingsaid dampers, shields adapted to entirely cover said side openings, said shields being open at the bottom, and fans in the upper enlarged part of said tube.
